| 摘要: | 热解技术是一种前景较好的城市生活垃圾资源化处理技术. 本研究对6种城市生活垃圾(木屑、纸张、米饭、菜叶、棉线和聚酯线)进行单一和混合组分热解, 探究温度对热解过程和产物炭性质的影响以及各组分之间的相互作用. 结果表明: (1)单一和混合组分热解的固体产率随温度升高逐渐降低, 气液产率则相反; (2)单一组分热解固体产物的灰分含量随温度升高先升后降, 在500~600℃时取得最大值, 挥发分随温度升高不断降低, 固定碳不断升高; (3)共热解时, 不同组分之间相互影响, 一种组分的热解受所加组分的影响, 表现出促进或抑制热解效果. |
| Abstract: | Pyrolysis is a promising technique for the treatment and reuse of municipal solid waste. In this study, six typical components of municipal solid waste (wood chips, paper, rice, vegetable leaves, cotton thread and polyester thread) are pyrolyzed individually and collectively in an effort to explore the pyrolysis process and product carbon properties as well as the interaction among the components with increasing temperature. Results show that (1) The solid yield of single and mixed components decreases with increasing temperature, while the gas and liquid yield increases accordingly. (2) The ash content of solid product of single components increases at first, and then decreases, reaching maximum value at 500-600℃. The fixed carbon content increases with elevating temperature while the volatile matter content decreases gradually. (3) The interactions among individual components have been found, which arise as the interactions can either foster or inhibit pyrolysis reactions. Those findings can provide theoretical and technical support for harmless treatment of municipal solid wastes. |
